PURPOSE:To carry out the hydrolysis of an oil or fat in high rate of hydrolysis, without causing the deactivation of enzyme, by placing an oil or fat suspending a lipase to one side of a separation membrane, placing water to the other side, and contacting the oil with water through the membrane, wherein the water in the water-phase is made to react in the form of steam. CONSTITUTION:An oil or fat suspending a lipase is placed to one side of a separation membrane, a water-phase is placed to the other side of the membrane, and the enzyme, the oil and the water are made to contact with each other through the membrane to effect the hydrolysis of the oil. In the above process, the water in the water-phase is made to react in the form of steam preferably by reducing the pressure. The pressure is preferably near or below the vapor pressure of water at the enzymatic reaction temperature.
